Dive Brief:

• Lamar Advertising is allowing everyone to share why they are #ThankfulThisHoliday on its billboards in the U.S. and Puerto Rico. 
• The outdoor advertising company is taking social media posts with photos and the hashtag #ThankfulThisHoliday and putting them up on the billboards. 
• Posts will also appear on a photo album on Lamar Advertising's Facebook page. 

Dive Insight: 

Hashtag campaigns are typically a good bet, but this one has some extra spark. The attention from social media is enough for most people to post, but the potential to be on a billboard could be even more enticing. The world of outside advertising is seeing some impressive innovation with more interactive and technology heavy features.
